Research Profile

My background in hydrocarbon exploration as a clastic sedimentologist, seismic stratigrapher and regional geologist have led me to the following three current lines of research:

1)       Fluid flow in sedimentary basins- The way in which fluids flow out of sedimentary basins  is sometimes expressed on seismic data as geometries or as changes in physical properties of the sediments detectable geophysically. It is of direct relevance to tracking mineralising solutions and hydrocarbon migration and indirectly may reveal the “deep plumbing” of sedimentary basins and the positions of reservoirs and aquifers. These clues on seismic data are not fully understood and hence are not currently used predictively. They could be.

2)       The depositional stratigraphy of organic rich mudstone sections is variable. At one extreme they may record simple pelagic rain-out and at the other be constrained for example by deep water erosional processes. Of course a whole range of possible stratigraphic geometries is present between these extremes. Clues from poorly sampled sedimentary systems are important in the early understanding of resource distribution and the planning of responsible exploitation of resources associated with organic rich units..

3)       In the Precambrian thick sandstone successions occur which have the hallmarks of shallow marine deposition. These sandstones or sometimes quartzites are very pure in the sense that they contain only extremely thin mudstone partings. How did Precambrian depositional processes achieve such a discrete separation between sand and mud deposition? Fieldwork on the critical and relatively rarely recorded coastal systems might hold the clue. Mapping and field work triggered by the recent interest in the Neo-Proterozoic glacigenic sequences and advances in provenance studies offer hope of solving this long-standing puzzle.
